my wife purchase this alarm clock for I for Christmas 2007 . it be the second piece of Coby electronic equipment that I have own . my experience be that Coby build extremely cheap -lrb- meaning , poor quality -rrb- product . my complaint with this product be : 1 -rrb- the product do not keep accurate time -lrb- gain about 7-8 minute per month - most likely a electronics design flaw that recur in each of these alarm clock -rrb- . 2 -rrb- the product `` hum '' through the speaker -lrb- a short in the internal electronics due to poor circuit board design - also a design flaw that probably recur in each of these alarm clock -rrb- . interestingly , when the product be power ON , like when the user want to listen to a cd but have not yet hit the play button , the hum quit . BUT , if the unit be leave ON accidentally , the alarm do NOT work . I know . I power the unit on to get the annoying hum to stop and be late to work the next day because the alarm never sound . 3 -rrb- CD door be overly difficult to open and close -lrb- a coefficient of friction design flaw that be also recur , probably -rrb- . 4 -rrb- the lead display be overly bright and no dimmer switch be feature -lrb- yet another design flaw -rrb- . 5 -rrb- all plastic part be extremely cheap . White plastic cabinet part be not the same color of white -lrb- do not match -rrb- . silver paint on button will obviously soon wear off , etc. . while this alarm clock have all of the feature that I be look for in a alarm clock -lrb- except for the dimmer switch -rrb- , the aforementioned list of design flaw force I to return the product as defective . bottom line : very cheaply build !
